DETAILED DESCRIPTION

Various implementations described herein are directed to various techniques for displaying thermocline data on a marine based display. These techniques may include receiving data from one or more sensors, wherein the data may include positional data, sonar data, and thermocline data. On a first portion of the display, these techniques may display a first image associated with chart data (e.g., a chart map) associated with a body of water (e.g., a lake) that identifies areas having a thermocline layer based on the positional data and the thermocline data. On a second portion of the display that is different than the first portion, these techniques may display a second image associated with the sonar data that identifies underwater features below a surface of the body of water along with the vertical depth of the thermocline layer based on the thermocline data. These techniques and various other details associated therewith are described in greater detail herein below.

Various implementations of displaying thermocline data will now be described in reference to FIGS. 1-7.

FIGS. 1-3 illustrate thermal characteristics associated with a body of water 102 in accordance with various implementations described herein. In particular, FIG. 1 illustrates various thermal layers 100 of the body of water 102, FIG. 2 illustrates a chart map image 200 (e.g., a top view) of the body of water 102, and FIG. 3 illustrates a sonar image 300 of the body of water 102 (e.g., a side view of a water column).

In reference to FIG. 1, the body of water 102 may include any type of water body, such as, e.g., an ocean, a lake, a stream, a pond, etc. Generally, the body of water 102 includes a surface 104 and a bottom or floor 106 with a column of water disposed therebetween. In some situations, this water column may include various thermal layers at various depths in the water column.

At a first depth 112 having upper and lower boundaries 114, 116, respectively, a first layer 110 may include an upper mixed layer (or region), which may be referred to as the epilimnion. The epilimnion may refer to a top-most layer in a thermally stratified lake. Due to close proximity to the surface 104, the epilimnion layer may receive substantial exposure to sunlight, and as such, the epilimnion layer may be a warmer layer than other lower layers in the thermally stratified lake. Further, the epilimnion layer may have a higher pH and a higher dissolved oxygen (O₂) concentration than the lower layers. Sometimes, at the surface 104, the epilimnion layer may exhibit turbulence due to surface wind-mixing. As such, at the surface 104, due in part to wind-mixing effects, the epilimnion layer may be free to exchange dissolved gases, such as, e.g., oxygen (O₂) and carbon-dioxide (CO₂) with the atmosphere.

At a second depth 122 having upper and lower boundaries 124,126, respectively, a second layer 120 may include a thermocline layer (or region), which may be referred to as the metalimnion. In some instances, the metalimnion may refer to a middle or intermediate layer in a thermally stratified lake. The thermocline layer refers to a distinct layer in a large body of water in which temperature may change rapidly with depth as opposed to other layers above or below. The thermocline layer may refer to or describe a thermal characteristic (or condition or feature) of a body of water in which thermocline occurs. Some factors that may affect depth and thickness (or vertical height) of the thermocline layer may include seasonal weather variations, geographic latitude, surface water heating and cooling, turbulence brought on by surface wind-mixing, and/or environmental conditions, such as water flow currents.

At a third depth 132 having upper and lower boundaries 134, 136, respectively, a third layer 130 may include a deep water layer (or region), which may be referred to as the hypolimnion. In some instances, the hypolimnion may refer to a dense, bottom layer of water in a thermally-stratified lake, and the hypolimnion layer may lie below the thermocline layer. The hypolimnion layer may be considered the coldest layer of a lake in summer seasons and the warmest layer during winter seasons. Due to its close proximity to the bottom or floor 106, the hypolimnion is somewhat isolated from surface wind-mixing and receives insufficient exposure to sunlight. In some instances, the hypolimnion layer may be warmer in lakes at warmer geographic latitudes.

Generally, during trolling, anglers search for fish in relation to the depth of the thermocline layer. In some situations, some bodies of water may have a thermocline layer at a same or approximately similar depth, and thus, an upper boundary of the thermocline layer may be identified with a lower boundary being the bottom or floor. In other situations, some bodies of water may not have or may not show evidence of a thermocline layer, and therefore, the thermocline layer may not be identified.

In reference to FIG. 2, the body of water 102 of FIG. 1 may be charted, and the chart map image 200 may be generated based on chart data (i.e., chart mapping data) derived or obtained from geo-positioning data, such as, e.g., global positioning data (GPS data). In some instances, the chart map 200 may be referred to as a schematic depiction or diagram designating surface features of Earth based regions, such as land and water based geographic objects, features, and regions. As shown in FIG. 2, the chart map image 200 may be viewed as a static two-dimensional representation of the body of water 102, as depicted from a position above the body of water 102.

As shown in FIG. 2, the chart map image 200 provides shading and highlighting to depict various contours and shapes of geographic objects, features, and regions. For instance, the chart map image 200 shows an identifiable water body image 210, such as, e.g., a lake, having lighter shading, surrounded by a land mass 212, having darker shading. In this instance, the contour of the water body is identifiable by an edge or demarcation line showing a separation between water and land. Further, within the boundaries of the water body image 210, highlighted areas of thermocline instances 220 are shown, so as to identify areas of thermocline in the water column. In this instance, these areas 220 provide a schematic view of the water body image 210 with a thermocline overlay that assists with identifying areas of thermocline in the water body.

In some implementations, highlighting may include use of coloring, e.g., using various different colors and/or using various color overlay options. In some other implementations, highlighting may include use of shading, e.g., using cross-hatching or various different grey-scale shading and/or blending and/or various grey-scale overlay options. Various other known highlighting techniques may also be used.

As shown in FIG. 3, the sonar image 300 may provide shading and highlighting to depict various contours and shapes of thermal layers or regions in the water column of the body of water 102 between a surface 104 and a bottom or floor 106. The sonar image 300 shows a side profile view of an identifiable water column 310 (e.g., of the lake in FIG. 2) having a lighter shading that depicts a thermocline layer 320 surrounded by an upper mixed layer 322, having a darker shading, and a lower deep water layer 324, also having darker shading. In this instance, the contour of the thermocline layer 320 is identifiable by an edge or demarcation area showing a separation between thermal layers. Further, within the boundaries of the water column 310, highlighted areas of the thermocline layer 320 are shown, so as to identify areas of thermocline in the water column 310. In this instance, these areas 320 provide a schematic view of the water column 310 with a thermocline overlay that may assist with identifying areas of thermocline in the water column 310.

FIG. 4 illustrates a multi-display of thermal characteristics associated with the body of water 102 in accordance with various implementations described herein.

In various implementations, techniques for displaying thermocline data may be performed or executed by various types of computing devices, such as, e.g., a computing device 640 as shown and described in reference to FIG. 6. Further, these techniques may be used in conjunction with a multi-function display (MFD), such as, e.g., a marine display or marine electronics device 700 as described in reference to FIG. 7.

For instance, the techniques described herein include receiving various marine electronics data from one or more sensors, such as, e.g., a sonar transducer a global positioning transceiver, etc. The marine electronics data may include various types of data, including positional data, sonar data, and/or thermocline data.

As shown in reference to FIG. 4, one or more marine based images may be displayed on a display. For instance, a first image 410 may be displayed on a first portion (e.g., left side) of a display. As shown, the first image 410 may be associated with chart data and may include a chart map of the body of water 102 (e.g., as described in reference to FIG. 2) that identifies areas having a thermocline layer 420 based on the positional data and the thermocline data. Further, a second image 430 may be displayed on a second portion (e.g., right side) of a display. As shown, the second image 430 may be associated with the sonar data that identifies underwater features below the surface 104 of the body of water 102 (e.g., as described in reference to FIG. 3) along with identifying a vertical depth of the thermocline layer 434 based on the thermocline data. The vertical depth of the thermocline layer 434 may be indicated or displayed as part of a vertical depth scale 432, wherein the approximate depth of thermocline layer 434 may be shaded, and approximate upper and lower boundaries 440, 442, respectively, may be identified on the vertical depth scale 432.

In some instances, a third image 450 may be displayed on a display, wherein the third image 450 may indicate, provide, or display data and information related to a current chart position 452, including longitude and latitude of a position as indicated with a window 412 in the chart map 410. Further, in some instances, the third image 450 may indicate, provide, or display data and information related to a thermocline upper boundary depth 454 (e.g., in feet and/or meters) of the approximate upper boundary 440 as shown or displayed in the vertical depth scale 432. Further, the third image 450 may indicate, provide, or display data and information related to a thermocline lower boundary depth 456 (e.g., in feet and/or meters) of the approximate lower boundary 442 as shown or displayed in the vertical depth scale 432.

FIGS. 5A-5B illustrate process flows of various methods for displaying thermal characteristics in accordance with various implementations described herein.

In particular, FIG. 5A illustrates a process flow diagram for a method 500 of displaying thermocline data in accordance with implementations of various techniques described herein. It should be understood that while method 500 indicates a particular order of execution of operations, in some instances, certain portions of the operations may be executed in a different order, and on different systems. Further, in some other instances, additional operations or steps may be added to method 500. Similarly, some operations or steps may be omitted.

Method 500 may be performed or executed by various types of computing devices, such as, e.g., the computing device 640 as shown and described in reference to FIG. 6. As described herein, the computing device 640 may be configured to interface with one or more sonar transducers, receive sonar data and thermocline data, and display various images associated therewith, including one or more images associated with sonar data and thermocline data. The computing device 640 may configured to interface with a GPS receiver (or transceiver), receive positional data (e.g., GPS data), and display one or more images associated therewith, including images associated with chart data (e.g., a chart data map) and positional data. Further, in some implementations, the techniques of method 500 may be used in conjunction with a multi-function display (MFD), such as, e.g., the marine display or the marine electronics device 700 as shown and described in reference to FIG. 7.

At block 502, method 500 may receive data from one or more sensors, wherein the data may include positional data, sonar data, and/or thermocline data. As described herein, a computing device may be implemented as a MFD that is configured to interface with the one or more sensors and receive the data from one or more sensors.

At block 504, on a first portion of a display, method 500 may display a first image associated with a chart map of a body of water that identifies areas having a thermocline layer based on the positional data and the thermocline data. The computing device may be configured to automatically identify areas of the body of water having the thermocline layer based on the positional and thermocline data and automatically display the first image on the display based on the positional and thermocline data. The first image may identify a current position on the body of water based on the positional data along with identifying areas of the body of water having the thermocline layer. The one or more sensors may include a GPS sensor, and the positional data may include GPS data received from the GPS sensor.

At block 506, on a second portion of the display that is different than the first portion, method 500 may display a second image associated with the sonar data that identifies underwater features below a surface of the body of water along with identifying a vertical depth of the thermocline layer based on the thermocline data. A computing device may be configured to automatically identify underwater features below a surface of the body of water based on the sonar data, automatically identify the vertical depth of the thermocline layer based on the thermocline data, and automatically display the second image on the display based on the sonar data and the thermocline data. The one or more sensors may include one or more sonar sensors, and the sonar data may include sonar scanning data received from the one or more sonar sensors. Further, the one or more sonar sensors may be configured to detect the thermocline layer in the body of water, and therefore, the sonar data may include the thermocline data received from the one or more sonar sensors. The one or more sonar sensors may include multiple transducer elements having one or more of a right scanning transducer, a left scanning transducer, a down scanning transducer, and a conical down beam transducer.

In some instances, a computing device may be configured to simultaneously display the first and second images on a split screen of a display. Further, the second image may be a sonar image having a shaded region that overlays a portion of the sonar image identified as the thermocline layer. The second image may include a sonar image having a vertical depth scale displayed along with the sonar image, and the vertical depth scale may provide information related to a depth of the thermocline layer. In some instances, the information related to the depth of the thermocline layer may include an indication for an upper boundary depth of the thermocline layer and another indication for a lower boundary depth of the thermocline layer.

FIG. 5B illustrates another process flow diagram for a method 520 of displaying thermocline data in accordance with implementations of various techniques described herein. It should be understood that while method 520 indicates a particular order of execution of operations, in some instances, certain portions of the operations may be executed in a different order, and on different systems. In some other instances, additional operations or steps may be added to method 520. Similarly, some operations or steps may be omitted. As with method 500 of FIG. 5A, method 550 of FIG. 5B may be performed or executed by various types of computing devices, such as, e.g., the computing device 640 as shown and described in reference to FIG. 6. Further, in some implementations, the techniques of method 500 may be used in conjunction with a multi-function display (MFD), such as, e.g., the marine display or the marine electronics device 700 as shown and described in reference to FIG. 7.

At block 522, method 520 may display a chart map associated with a body of water. For instance, as shown in reference to FIGS. 2 and 4, the chart map image 200, 410 may be associated with the body of water 210, such as, e.g., a lake, surrounded by a land mass 212. In some implementations, as shown in reference to FIG. 4, the chart map 410 may be displayed on a left-hand side of a display.

At block 524, method 520 may receive a request to activate (e.g., turn on) a thermocline overlay associated with the chart map. For instance, as shown in reference to FIG. 7, the marine display or marine electronics device 700 may include one or more buttons 720, wherein at least one of the buttons 720 may be configured to activate or turn on the thermocline overlay upon selection by a user (e.g., an angler).

At block 526, method 520 may identify a thermocline region associated with the body of water from sonar data received from one or more sonar transducers. For instance, as shown in reference to FIGS. 3 and 4, the sonar image 300, 430 may be associated with the column of water 310, such as, e.g., a column of water in a lake, as depicted, e.g., in the chart map image 200, 410. In some implementations, as shown in reference to FIG. 4, the sonar image 430 may be displayed on a right-hand side of a display along with the chart map image 410 displayed on the left-hand side.

At block 528, method 520 may determine a depth range corresponding to the thermocline region associated with the body of water as identified from the sonar data. For instance, as shown in reference to FIGS. 3 and 4, the sonar image 300, 430 may be associated with the column of water 310, and a vertical depth range or scale 432 of the thermocline layer 434 may be displayed with a shaded area or region along with the sonar image 300, 430. In some implementations, as shown in reference to FIG. 4, the thermocline layer 434 may be implemented as an overlay (as shown with shading) on the sonar image 430, and the thermocline layer overlay 434 may correspond to the vertical depth scale 432. In this instance, the shading may further overlay the vertical depth scale 432 to show an approximate depth of the thermocline layer 434 along with approximate upper and lower boundaries 440, 442, respectively, of the thermocline layer 434.

At block 530, method 520 may highlight areas on the chart map associated with the body of water corresponding to the thermocline region. For instance, as shown in reference to FIGS. 2 and 4, the chart map image 200, 410 may include highlighted areas or regions 420 showing parts of the body of water having a thermocline layer. Further, in another instance, as shown in reference to FIGS. 3 and 4, the sonar image 300, 430 may include highlighted areas or regions 434 showing parts of the column of water having a thermocline layer, e.g., as indicated by the shaded cross-hatching.

FIG. 6 illustrates a diagram of thermal display system 600 in accordance with various implementations described herein.

In reference to FIG. 6, the thermal display system 600 may include at least one transducer 610, a computing device 640, and a network server 690. The transducer 610 may be configured to provide sonar data 612 (e.g., various types of scanning sonar data) corresponding to a position of a watercraft (e.g., vessel, boat, ship, etc.) in a body of water. In some implementations, the transducer 610 may include a spotlight transducer array having multiple scanning transducers. In other implementations, the transducer 610 may include multiple sonar scanning transducer elements, including one or more of a right scanning transducer, a left scanning transducer, a down scanning transducer, and/or a conical down beam transducer.

During operation, the transducer 610 may be configured to use sonar for imaging various environmental features (e.g., fish, plants, rocks, lures, bait, etc.) in a body of water. This imaging may include mapping an underwater environment below a surface of the body of water between the surface and a bottom or floor of the body of water. For instance, this imaging may include various sonar images of fish or schools of fish captured beneath a watercraft by the transducer 610 in any direction.

The transducer 610 may be configured to directly provide the sonar data 612 to the computing device 640. Further, the computing device 640 may be configured to receive the sonar data 612 from the transducer 610 over a wired or wireless network via a network interface 660. As described herein, the sonar data 612 may include data related to thermal characteristics of a body of water (e.g., thermocline related data). Further, as described herein, the sonar data and thermocline data may be associated with chart data including, e.g., chart map data associated with a body of water.

In some implementations, the transducer 610 may be configured to provide various angular ranges of view in multiple directions, such as, e.g., approximately a 90° vertical view along with approximately a 15° to 30° horizontal view. The various angular ranges of view may include or at least be extended to include angular ranges of vertical views from/between 0° to more than 90° along with angular ranges of horizontal views from/between 0° to 180°. In some instances, the transducer 610 may be configured to manually or automatically rotate vertically and/or horizontally so as to rotate the view.

Generally, the term sonar (i.e., SOund Navigation And Ranging) may refer to various techniques for propagating sound underwater to detect objects on or under a surface of a body of water, such as fish, lures, plants, rocks, sea floor, etc. One type of sonar technology refers to active sonar that is configured to emit pulses of sound waves while receiving echoes, which refers to pinging. Sonar may be used to determine acoustic locations and/or measurements of echo characteristics for targets and objects in a body of water. Further, acoustic frequencies used in sonar based devices may vary from low frequency (i.e., infrasonic) to high frequency (i.e., ultrasonic).

In various implementations, the transducer 610 may include one or more sonar traducer elements. Each sonar transducer element (including sonar scanning elements) may be configured to use sonar technology to evaluate attributes of various target objects by interpreting echoes from sound waves. Further, each sonar transducer element may be configured to actively generate low and/or high frequency sound waves and evaluate reflected echoes to thereby measure time intervals between sending signals and receiving corresponding echoes to determine distance to target objects. Each sonar transducer element may be configured to convert energy into sound waves using piezoelectric transducers or capacitive transducers that are configured to convert electrical energy into sound. Each sonar transducer element may be configured to use piezoelectric crystals that include a property of changing size when voltage is applied, whereby applying an alternating current (AC) across the piezoelectric crystals may cause oscillations at high frequencies, to thereby generate high frequency sound waves. In some instances, focusing sound waves generated by each sonar transducer element may be determined by an area and shape of each sonar transducer element, a sound wave frequency of each sonar transducer element, and a sound velocity of the propagation medium, such as a body of water. In some instances, each sonar transducer element may use piezoelectric crystals configured as transceivers to transmit and detect sound waves in one or more elements, such as propagating sound waves and receiving echoing sound waves.

In some implementations, the transducer 610 may be electrically coupled to the computing device 640 via one or more electrical wires or cables (not shown). Further, the computing device 640 may be configured to store/record sonar data received from the transducer 610 via the electrical cables. The computing device 640 may be configured to control operation of a watercraft. In some instances, operation of the watercraft may be controlled by the computing device 640 including user interaction with the computing device 640. In some other instances, operation of the watercraft may be controlled via user interaction with a foot-pedal (not shown) positioned on the watercraft.

In some implementations, the transducer 610 may include one or more sensors (not shown). For instance, the one or more sensors may include a dedicated sensor (e.g., water sensor) configured for sensing deployment and/or removal of the transducer 610 in and/or from the body of water 102. In this instance, the dedicated sensor may include electrode terminals (not shown) configured to activate (e.g., power-up) the transducer 610 when the watercraft is deployed in water. The electrode terminals may be configured to deactivate (e.g., power-down) the transducer 610 when the watercraft is removed or withdrawn from water. Further, in some instances, the one or more sensors may include one or more environmental sensors, such as a temperature sensor.

The computing device 640 may include at least one processor 642 and memory 644 having instructions that cause the processor 642 to display images associated with the sonar data 612 on a display component or device 670. The instructions may cause the processor 642 to simultaneously display multiple images associated with the sonar data 612 and other related data (e.g., chart map data) on the display device 670 in a split screen mode of operation, as described herein. Further, the computing device 640 may be configured to create/generate sonar logs associated with the sonar data 612.

The computing device 640 may include a thermal display module 662 that may be configured to display thermal characteristics of a body of water, such as, e.g., data related to a thermocline layer or region of the body of water. The thermal display module 662 may be configured to display chart data (e.g., chart map data) along with sonar data and/or thermocline data associated with the body of water. In some implementations, the thermocline data may be displayed along with the chart data and/or the sonar data as an overlay. For instance, thermocline data may be displayed as an image that overlays an image of a chart map and/or overlays an image of sonar data. These various images may be displayed on a display (e.g., MFD or other marine electronics device or display) and thus used to provide a view to an angler (e.g., fisherman, boat captain, or other user).

The computing device 640 may be configured to store/record sonar data 612 and/or sonar logs in one or more databases (e.g., database 680). The computing device 640 may be configured to upload the sonar data 612 and/or sonar logs to the network server 690, such as, e.g., a cloud server or other network server, via the network interface 660. The computing device 640 may be configured to store/record multiple sonar logs and create/generate a map therefrom. The computing device 640 and/or network server 690 may be configured to create/generate one or more maps by stitching (e.g., combining or joining) multiple sonar logs together. The computing device 640 may be configured to receive geo-coordinate data 652, such as global positioning system data (i.e., GPS data), via a GPS transceiver 650 and associate the received GPS data to the sonar data 612, sonar logs, and/or maps at any time, including prior to upload. In various instances, the wired or wireless network may include any type of wired or wireless communication network and/or cloud based network.

In various implementations, the computing device 640 may be configured as a special purpose machine for interfacing with one or multiple sonar transducers, such as, e.g., more than one transducer 610. The computing device 640 may configured to display one or more images (including simultaneous display of multiple images) associated with sonar data, thermal data (e.g., thermocline data), and/or chart map data associated with a body of water. Further, the computing device 640 may include standard elements and/or components, including the at least one processor 642, the memory 644 (e.g., non-transitory computer-readable storage medium), at least one database 680, power, peripherals, and various other computing elements and/or components that may not be specifically shown in FIG. 6. The computing device 640 may include the display device 670 (e.g., a monitor or other display) that may be used to provide a user interface (UI) 672, including a graphical user interface (GUI). In FIG. 6, the display 670 is shown as an incorporated part of the computing device 304; however, the display 670 may be implemented as a separate component. Further, the UI 672 may be used to receive one or more preferences from a user of the display device 670 for managing or utilizing the system 600, including interfacing with the transducer 610. As such, a user may setup desired behavior of the computing system 600 and/or transducer 610 via user-selected preferences using the UI 672 associated with the display device 670. Moreover, various elements and/or components of the system 600 that may be useful for the purpose of implementing the thermal display system 600 and components thereof may be added, included, and/or interchanged, in a manner as described herein.
